There's nothing quite like the aroma of beef and barley soup simmering on the stove on a cold afternoon. I've been making this recipe for over fifteen years, and it never fails to fill the house with the most incredible smell. My grandmother used to make something similar, though she'd throw in whatever vegetables were hanging around the kitchen. This soup has its roots in Eastern European Jewish cooking, where barley was a staple grain that could stretch a pot of soup to feed a large family. The key to getting the deep, rich flavor is taking your time with the initial browning of the beef. Don't rush this step. I use chuck roast cut into chunks because it gets so tender after the long simmer, and the marbling adds incredible flavor to the broth. What makes this version work particularly well is the timing. I add the barley about halfway through cooking so it doesn't get mushy, and I save some of the vegetables for the last 30 minutes. This gives you different textures in every spoonful. The carrots stay slightly firm, the celery adds crunch, and the barley has that perfect chewy texture. This soup is perfect for Shabbat lunch or any time you want something that'll warm you from the inside out. I usually serve it with fresh challah or some crusty bread. It also freezes beautifully, though the barley will absorb more liquid as it sits, so you might need to add extra broth when reheating.
